"Sources tell us Young's body was discovered with a gun shot wound that appears to be self-inflicted," reports TMZ, who broke the story.
Young currently plays Detective Barry Frost on the TNT show "Rizzoli & Isles" and after he didn't show up for work this morning, staffers called the actor's landlord to check up on him.
"When the landlord opened the door," reports TMZ, "he discovered Young's body."
Young also starred as Chris Comer in the 2004 film "Friday Night Lights" and played Alex Bauer on the TV series "South Beach."
